Abstract:During this seminar, we will give a panorama of our recent achievements in the preparation of oxide structures, perovskites and lead-free perovskite related materials. We will show the high possibilities, high control and versatility of solution growth techniques for the preparation of materials with the desired properties.

For the perovskite solar cells, we will illustrate the great importance of the interfaces and selective contact properties for reaching high efficiencies. We will also present results on and estimate the potential of iodobismuthates for an application as an absorber in perovskite solar cells. Due to its surface reactivity and sensitivity as well as its easiness to shape by solution growth method, zinc oxide is a semiconductor material of choice in nanoscience and nanotechnologies. It will be illustrated by the description of nanowire preparations and their integration in nanosensor devices with a remarkably high response and sensitivity to hydrogen.
